What are the disadvantages of keyless entry?

[DelBarrett]

Keyless entry is susceptible to interference and shielding. When the car system is interfered with, it cannot recognize the smart key, preventing automatic door opening and vehicle startup. Another common issue is frequently forgetting to take the smart key. Precautions for keyless start: 1. Do not place it with electronic devices: Since smart keys use low-intensity radio waves, they may malfunction under magnetic interference. Regularly placing the smart car key with a mobile phone can cause interference from the phone's frequency, leading to malfunction. If the smart key receives high-intensity radio waves, it may excessively drain the battery. Therefore, avoid placing the smart key near TVs, computers, or similar devices. 2. Water damage to the smart car key: If the smart car key gets wet, it can burn out internal circuits and cause malfunction. In case of water exposure, open the casing, lay it flat, and use a hairdryer to dry it before taking it to a repair shop for inspection. Avoid shaking the key vigorously, as this can easily spread water to other critical circuits, and do not immediately use the remote to unlock, as this may burn out the circuit board.
